GASEMENT ADJUSTER FOR SWINGING SASHES OR SHUTTERS.

Application filed July 26, 1922. Serial No. 577,575.

To all whom it may concern:

Be it known that I, CHRISTOPHER V. RAIOEVICH, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Casement Adjusters for Swinging Sashes or Shutters, of which the following is a specification.

My invention relates to improved means for opening and closing, and for adjusting the extent of opening, of a window casement of that type which swings outwards on hinges. With such easements it is desirable to adjust the same to any desired position from the fully open to the fully closed, and to hold the same firmly in such position against the normal action of wind, rain or the like. I

My invention comprises a certain novel arrangement and certain novel combinations of parts which will be hereinafter more fully described and claimed.

Reference is had to the accompanying drawings, in which like parts are indicated by similar reference symbols throughout the several views, and in which Figure 1 is a plan view, partly in section through the easement, showing the sash in the closed position in full lines, and in the fully open position in dotted lines, part of the guide rail being broken away to show the head of the sliding pivot block.

-Figure 2 is a detail view showing in perspective, and on a larger scale, the sliding pivot block which is connected to the sash.

Figure 3 is a detail showing in perspective the detachable head for the sliding block which engages in the guide rail.

Figure 4 is a top plan view of the sliding pivot block with the detachable head connected thereto, said head being shown in section.

Figure 5 shows a section along the line i 5-5 of Fig. 1, and looking in the direction of the arrows, the parts being shown on a larger scale.

Figure 6 shows a section along the line 6-6 of Fig. 1, and looking in the direction of the arrows,

Figure 7 is an enlarged plan view of the operating handle, parts beingbroken away to show the rack above, which is mounted on the window sill.

Figure 8 shows a section along the line 8-8 of Fig. 6, and looking in the direction of the arrows; and

Figure 9 is a detail view showing the guide rail removed from the sash.

A represents the window frame, A the window sill, B the window sash which is hinged to the frame, as at C, and swings outwards in the usual way. said sash being shown as provided with glass B.

D represents the guide rail fast to the lower edge of the sash and provided with a slot d in the inner side thereof to permit the travel of the sliding pivot block E. This ivot block is preferably provided with a ug 0, provided with a pinhole e, and with a lug e? provided with a tenon 6 which lugs project, respectively, into the slots f and f of an adjustable head F which is preferably formed of a sheet of resilient metal, having its ends bent, as shown at 7, f and f. to form a light hollow guide head for the sliding pivot block. This guide head slides in the guideway of the guide rail D. Owing to its hollow resilient'construction, this guide head is not apt to become jammed in the guide rail no matter what may be the position of the sash. The lug e fits snugly in the slot 7, and the lug 6 passes up through the elongated slot f, the parts when connected together being in the position shown in Fig. 4

Below is provided with a guide rib e which slides in the slot (Z of the guide rail. This block E is also provided with outwardly projecting lugs 0 perforated as at e to receive the pivot pin E to which the arm H of the operating handle ll is pivotally connected. This operating handle is provided with a hand lever H and is pivoted on the central stud I of the rack I, which is secured to the window sill A in any convenient way. as by means of the flange I and the bolts J. see Figs. 1 and 7.

The operating handle is provided with an enlarged central portion or casing H surrounding the pivot I, and this portion is provided with a downwardly projecting arcuate rib h, adapted to engage the guide groove 2' outside of the rack 1 see Fig. 6. This rack is in the form of an arc of a circle, as shown in Fig. 7 concentric with the pivot stud I. This pivot stud is preferably rethe head F the sliding pivot block duced at its upper-end i to enga e the metal stra K, shown most clearly in %igs. 5 and 7, w ich strap has its ends is secured to the window sill as by means of the bolts L. This stra prevents the handle from being accidentally removed from the rack bar.

The arm H of the handle is provided with a guide groove k to receive the pawl M, which may be either gravity operated or spring operated. This pawl is shown in Fig. 6 as gravity operated, and is hinged to the arm H, as at m, and has its free end provided with a tooth m adapted to engage the teeth of the rack I. ThlS pawl may be disengaged, when it is desired to turn the handle about its pivot, by simply pressing up on said awl, and when the pawl is released it wil fall by its own weight into engagement with the rack teeth, as shown in ig. 6. If a positive lock is desired, a spring impressed pawl may be used, such as are well known in the art.

In order to limit the angle through which the handle may be rotated, I may provide a lug h projecting downwardly into the casing H, as shown in Figs. 6 and 7, which lug engages stop lugs i and i, rojecting from the pivot stud I of the rac block I, as shown in dotted lines in Fi 7.

The operation of the device 1s as follows:

The sash being in the closed position shown in full lines in Fig. 1, if it is desired to 0 en same grasp the arm H with the ham in so doing the pawl M will be lifted from engagement with the rack, and the sash may be swung outwards by swinging the arm H to the right of Fig. 1. If the be automatically locked when the sash sticks, pressure outwards ma be applied to the same with the' right han using the left hand to swing the and H As the sash swings outwards, the sliding pivot block E A will draw the head F to the left in the guide rail D and when the sash isfully open the parts will be, inthe position as indicated in otted lines in Fig. 1. I The sash maybe moved to the fullyopen or any intermediate open position, and will 7 pawl M is released. Obviously the parts shding in the uide rail D should be suitably lubricate Theresilient loops of the sliding head F will not only' revent'those parts from jamming, but will also in a large measure obviate rattling due to variations in wind pressure.

It will be noted that the device hereinbefore described may be applied to any swingthe building as they are ordinarily constructed. a

The device may be applied to the swinging sash of 'a shutter, and to the window sill by the use of simple tools and may be conveniently taken ofl when its use is no longer desired. Thus, for instance, the device may be applied in the summer and taken off when cold weather comes, or it may be left permanently attached to the window as desired.

It will be obvious that various modifications might be made in the herein described construction, and in the combination and arrangement of parts which could be used Without departing from the spirit of my invention; and I do not mean to limit the invention to such details except as particularly pointed out in the claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is 1. An attachment for adjusting swinging sashes, shutters or the like in the desired position comprising a hollow guide rail secured to the swinging sash, a pivot block slidably connected tosaid guide rail said pivot block including a body portion and a detachable head made of a strip or resilient bent metal adapted to engage in said track rail, a segmental rack secured to thewindow or door frame and provided with a central pivot, an operating bar having one end pivoted to the body portion of said pivot block and the other end terminating in a handle, the said operating bar-being pivoted above said rack, and a pawl pivoted to said handle and normally engaging said rack, but adapted to be withdrawn from such engagement when said handle is gripped b the operator.

2. An attachment for adjusting swinging sashes, shutters or the like in the desired position comprising a hollow guide rail secured to the swinging sash, a pivot block slidabl connected to said uide rail said pivot lock including a ho y portion and a detachable head made of a strip of resilient bent metal adapted to engage in said track rail, a segmental rack secured to the window or door frame and provided with a central pivot, an operating bar having one end ivoted to the body portion of said pivot block and the other end terminating in a hollow handle, the said operating bar being I ivoted above said rack, and a pawl pivoted 1n the hollow portion of said handle and normally en aging said rack, but adapted to be with rawn from such engagement when said handle is gripped by .the operator.
